On 30th April 2020 Angus Energy wrote to WSCC withdrawing their latest application for the 3 year well test at Balcombe.

Dear Chris and Jane,
I hope you remain well since we last spoke.
After internal discussions we have decided to today withdraw our application for Planning
Permission at Balcombe.
Please take this email as confirmation of withdrawal.
We will be in touch shortly to discuss next steps, and the way forward in order to progress the
Balcombe Project.
I would be grateful if you could confirm receipt of this email as soon as possible.

Chris Bartlett of WSCC Planning Department replied confirming withdrawal of the application.

The planning application was recommended for refusal and did not ever reach the planning committee.
